Although I thought that it was cheaper to purchase it collectively, even if I bought it separately at a neighborhood store, it is cheap such as one 88 yen, and although I thought that it was cheaper than anything, I bought it briefly though I bought it a bit. .
Since the purpose of use is marking of the defective part originally it is not used much. I ordered one box, but I think that it would be better to be able to order smaller quantities. If I am in the current amount, I feel that I can use it for about 10 years when I order it once.
